Procedure

A pressure tube was charged with benzyl {7-bromo-2-[({4-[(3R,4S,5S)-3-[(tert-butoxycarbonyl)amino]-5-methyl-4-(1H-1,2,3-triazol-1-yl)piperidin-1-yl]pyridin-3-yl}amino)carbonyl]quinolin-3-yl}carbamate (15 mg, 0.020 mmol), K3PO4 (8.4 mg, 0.034 mmol), 1,4-dioxane (0.3 mL), water (0.04 mL) and 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,6-tetrahydropyridine (6.6 mg, 0.03 mmol). The reaction mixture was purged with nitrogen for 5 min., then dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine-(2′-aminobiphenyl-2-yl)(chloro)palladium (1:1) (1.6 mg, 0.002 mmol) was added. The reaction mixture was sealed and heated at 90° C. for 30 min., then allowed to cool to room temperature. The crude mixture was filtered and purified by preparative LCMS (pH=10 method; XBridge™ preparative C18 5 μm OBD™ column, 30×10 mm, 60 mL/min., eluting with a gradient of MeCN and water with 0.1% NH4OH) to give the title compound as a light yellow powder (4.7 mg, 33%). LCMS calc. for C42H49N10O5 (M+H)+: m/z=773.4. Found: 773.4.
